XEP-0332: HTTP over XMPP transport

default_config: ClassVar[Dict[str, Any]] = {'supported_headers': {'Accept', 'Accept-Charset', 'Accept-Encoding', 'Content-Encoding', 'Content-ID', 'Content-Language', 'Content-Length', 'Content-Location', 'Content-Transfer-Encoding', 'Content-Type', 'Date', 'DateTime', 'Description', 'Distribute', 'ETag', 'Error-Info', 'Expect', 'Expires', 'Host', 'Identifier', 'Location', 'Proxy-Authenticate', 'Proxy-Authorization', 'Server', 'Timestamp', 'Transfer-Encoding', 'User-Agent', 'WWW-Authenticate'}}#

TODO: Do we really need to mention the supported_headers?!

dependencies: ClassVar[Set[str]] = {'xep_0030', 'xep_0131'}#

xep_0047 not included. xep_0001, 0137 and 0166 are missing

Stanza elements#

class slixmpp.plugins.xep_0332.stanza.data.HTTPData(xml=None, parent=None)[source]#

The data element.

get_data(encoding='text')[source]#
interfaces: ClassVar[Set[str]] = {'data'}#

The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the plugin_attrib value of any registered stanza plugins.

is_extension: ClassVar[bool] = True#

If you need to add a new interface to an existing stanza, you can create a plugin and set is_extension = True. Be sure to set the plugin_attrib value to the desired interface name, and that it is the only interface listed in interfaces. Requests for the new interface from the parent stanza will be passed to the plugin directly.

New in version 1.0-Beta5.

iterables: List[ElementBase]#

A list of child stanzas whose class is included in plugin_iterables.

loaded_plugins: Set[str]#
name: ClassVar[str] = 'data'#

The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'urn:xmpp:http'#

The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

parent: Optional[ReferenceType[ElementBase]]#

A weakref.weakref to the parent stanza, if there is one. If not, then parent is None.

plugin_attrib: ClassVar[str] = 'data'#

For ElementBase subclasses which are intended to be used as plugins, the plugin_attrib value defines the plugin name. Plugins may be accessed by using the plugin_attrib value as the interface. An example using plugin_attrib = 'foo':

register_stanza_plugin(Message, FooPlugin)
msg = Message()
msg['foo']['an_interface_from_the_foo_plugin']
plugins: Dict[Tuple[str, Optional[str]], ElementBase]#

An ordered dictionary of plugin stanzas, mapped by their plugin_attrib value.

set_data(data, encoding='text')[source]#
tag: str#

The name of the tag for the stanza’s root element. It is the same as calling tag_name() and is formatted as '{namespace}elementname'.

xml: ET.Element#

The underlying XML object for the stanza. It is a standard xml.etree.ElementTree object.

class slixmpp.plugins.xep_0332.stanza.request.HTTPRequest(xml=None, parent=None)[source]#

All HTTP communication is done using the Request/Response paradigm. Each HTTP Request is made sending an iq stanza containing a req element to the server. Each iq stanza sent is of type set.

Examples:

<iq type='set' from='a@b.com/browser' to='x@y.com' id='1'>
    <req xmlns='urn:xmpp:http'
         method='GET'
         resource='/api/users'
         version='1.1'>
        <headers xmlns='http://jabber.org/protocol/shim'>
            <header name='Host'>b.com</header>
        </headers>
    </req>
</iq>

<iq type='set' from='a@b.com/browser' to='x@y.com' id='2'>
    <req xmlns='urn:xmpp:http'
         method='PUT'
         resource='/api/users'
         version='1.1'>
        <headers xmlns='http://jabber.org/protocol/shim'>
            <header name='Host'>b.com</header>
            <header name='Content-Type'>text/html</header>
            <header name='Content-Length'>...</header>
        </headers>
        <data>
            <text>...</text>
        </data>
    </req>
</iq>
get_method()[source]#
get_resource()[source]#
get_version()[source]#
interfaces: ClassVar[Set[str]] = {'method', 'resource', 'version'}#

The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the plugin_attrib value of any registered stanza plugins.

iterables: List[ElementBase]#

A list of child stanzas whose class is included in plugin_iterables.

loaded_plugins: Set[str]#
name: ClassVar[str] = 'request'#

The XML tag name of the element, not including any namespace prefixes. For example, an ElementBase object for <message /> would use name = 'message'.

namespace: str = 'urn:xmpp:http'#

The XML namespace for the element. Given <foo xmlns="bar" />, then namespace = "bar" should be used. The default namespace is jabber:client since this is being used in an XMPP library.

parent: Optional[ReferenceType[ElementBase]]#

A weakref.weakref to the parent stanza, if there is one. If not, then parent is None.

plugin_attrib: ClassVar[str] = 'http-req'#

For ElementBase subclasses which are intended to be used as plugins, the plugin_attrib value defines the plugin name. Plugins may be accessed by using the plugin_attrib value as the interface. An example using plugin_attrib = 'foo':

register_stanza_plugin(Message, FooPlugin)
msg = Message()
msg['foo']['an_interface_from_the_foo_plugin']
plugins: Dict[Tuple[str, Optional[str]], ElementBase]#

An ordered dictionary of plugin stanzas, mapped by their plugin_attrib value.

set_method(method)[source]#
set_resource(resource)[source]#
set_version(version='1.1')[source]#
tag: str#

The name of the tag for the stanza’s root element. It is the same as calling tag_name() and is formatted as '{namespace}elementname'.

xml: ET.Element#

The underlying XML object for the stanza. It is a standard xml.etree.ElementTree object.

class slixmpp.plugins.xep_0332.stanza.response.HTTPResponse(xml=None, parent=None)[source]#

When the HTTP Server responds, it does so by sending an iq stanza response (type=`result`) back to the client containing the resp element. Since response are asynchronous, and since multiple requests may be active at the same time, responses may be returned in a different order than the in which the original requests were made.

Examples:

<iq type='result'
    from='httpserver@clayster.com'
    to='httpclient@clayster.com/browser' id='2'>
    <resp xmlns='urn:xmpp:http'
          version='1.1'
          statusCode='200'
          statusMessage='OK'>
        <headers xmlns='http://jabber.org/protocol/shim'>
            <header name='Date'>Fri, 03 May 2013 16:39:54GMT-4</header>
            <header name='Server'>Clayster</header>
            <header name='Content-Type'>text/turtle</header>
            <header name='Content-Length'>...</header>
            <header name='Connection'>Close</header>
        </headers>
        <data>

                ...
